Route calculation and PTV_TruckAttributes

[fstrahberger]

Hello,
I have a question about routing with PTV_TruckAttributes enabled. When this feature is enabled then all truck features are considered as blocking even when the vehicle does not violate the restrictions.

So I tried the example from the manuals. The example request is based on the Routing Use Case „How to Use Feature Layer Theme PTV_TruckAttributes“.

The manual states that the route for a vehicle with maxHeight=150 will be routed through a height (460 cm) restricted area. The route should be about 800 meters.

Here ist he JSON-Request:

Code: Select all

{
  "waypoints": [
    {
      "$type": "WaypointDesc",
      "linkType": "NEXT_SEGMENT",
      "fuzzyRadius": 0,
      "coords": [
        {
          "$type": "Point",
          "point": {
            "$type": "PlainPoint",
            "x": 5.995894,
            "y": 49.510518
          }
        }
      ]
    },
    {
      "$type": "WaypointDesc",
      "linkType": "NEXT_SEGMENT",
      "fuzzyRadius": 0,
      "coords": [
        {
          "$type": "Point",
          "point": {
            "$type": "PlainPoint",
            "x": 5.999437,
            "y": 49.50566
          }
        }
      ]
    }
  ],
  "details": {
    "segments": true,
    "featureDescriptions": true
  },
  "callerContext": {
    "properties": [
      {
        "key": "CoordFormat",
        "value": "OG_GEODECIMAL"
      },
      {
        "key": "ProfileXMLSnippet",
        "value": "<Profile xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'><FeatureLayer majorVersion='1' minorVersion='0'><Themes><Theme id='PTV_TruckAttributes' enabled='true'/></Themes></FeatureLayer><Routing majorVersion='2' minorVersion='0'><Course><AdditionalDataRules enabled='true'/></Course><Vehicle><Physical><Dimension maxHeight='150'/></Physical></Vehicle></Routing></Profile>"
      }
    ]
  }
}

But the route is about 4000 meter although the maxHeight oft he vehicle was set to 150 cm:

Code: Select all

"info": {
    "distance": 4033,
    "time": 347,
    "cost": 4223
  },

The only option to get a route through the height restricted segment is to allow seqment violation:

Code: Select all

{
  "waypoints": [
    {
      "$type": "WaypointDesc",
      "linkType": "NEXT_SEGMENT",
      "fuzzyRadius": 0,
      "coords": [
        {
          "$type": "Point",
          "point": {
            "$type": "PlainPoint",
            "x": 5.995894,
            "y": 49.510518
          }
        }
      ]
    },
    {
      "$type": "WaypointDesc",
      "linkType": "NEXT_SEGMENT",
      "fuzzyRadius": 0,
      "coords": [
        {
          "$type": "Point",
          "point": {
            "$type": "PlainPoint",
            "x": 5.999437,
            "y": 49.50566
          }
        }
      ]
    }
  ],
  "details": {
    "segments": true,
    "featureDescriptions": true
  },
  "options": [
    {
      "parameter": "ALLOW_SEGMENT_VIOLATIONS",
      "value": "true"
    },
    {
      "parameter": "COST_OF_SEGMENT_VIOLATIONS",
      "value": "0"
    }
  ],
  "callerContext": {
    "properties": [
      {
        "key": "CoordFormat",
        "value": "OG_GEODECIMAL"
      },
      {
        "key": "ProfileXMLSnippet",
        "value": "<Profile xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'><FeatureLayer majorVersion='1' minorVersion='0'><Themes><Theme id='PTV_TruckAttributes' enabled='true'/></Themes></FeatureLayer><Routing majorVersion='2' minorVersion='0'><Course><AdditionalDataRules enabled='true'/></Course><Vehicle><Physical><Dimension maxHeight='150'/></Physical></Vehicle></Routing></Profile>"
      }
    ]
  }
}

Then the route is shorter but contains violations:

Code: Select all

"info": {
    "distance": 845,
    "time": 105,
    "cost": 1210,
    "hasViolations": true
  },

Here is an example of one violating segment:

Code: Select all

{
      "firstPolyIdx": 14,
      "polyC": 2,
      "firstNodeIdx": 9,
      "nodeC": 2,
      "streetNoIdx": -1,
      "streetNameIdx": -1,
      "dirInfoIdx": -1,
      "accTime": 90,
      "accDist": 720,
      "iuCode": 52,
      "countryCode": "",
      "violations": [
        "FeatureLayer:themeId=PTV_TruckAttributes|ruleId=ptvTA_BM_2|maxHeight=460"
      ],
      "featureDescriptions": [
        {
          "themeId": "PTV_TruckAttributes",
          "description": "driveType=0|maxHeight=460"
        }
      ],
      "nC": "CITY_ROAD",
      "vNorm": 0
    },

What could be the cause of this calculation/violation? I would expect that the Parameter maxHeight=150 would allow Routing throught the height restricted seqment?

Thanks in advance!

In you snippet you are using the attribute maxHeigth='150'. This should heigth='150'.

[Joost]

Also, did you alter your default profile? I was kind of suprised that the internal setting for heigth was bigger then the 460 so I checked this and it isn't. When I ran you request against our cloud I always get the shorter route.

[fstrahberger]

Hallo Joost,

many thanks for your answer.

I have changed maxHeigth='150' to heigth='150' - it still calculates the longer route.

Next I have added all Physical attributes from Default.xml to the request - xRoute still calculates the longer route.

Code: Select all

{
  "waypoints": [
    {
      "$type": "WaypointDesc",
      "linkType": "NEXT_SEGMENT",
      "fuzzyRadius": 0,
      "coords": [
        {
          "$type": "Point",
          "point": {
            "$type": "PlainPoint",
            "x": 5.995894,
            "y": 49.510518
          }
        }
      ]
    },
    {
      "$type": "WaypointDesc",
      "linkType": "NEXT_SEGMENT",
      "fuzzyRadius": 0,
      "coords": [
        {
          "$type": "Point",
          "point": {
            "$type": "PlainPoint",
            "x": 5.999437,
            "y": 49.50566
          }
        }
      ]
    }
  ],
  "details": {
    "segments": true,
    "featureDescriptions": true
  },
  "callerContext": {
    "properties": [
      {
        "key": "CoordFormat",
        "value": "OG_GEODECIMAL"
      },
      {
        "key": "ProfileXMLSnippet",
        "value": "<Profile xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'><FeatureLayer majorVersion='1' minorVersion='0'><Themes><Theme id='PTV_TruckAttributes' enabled='true'/></Themes></FeatureLayer><Routing majorVersion='2' minorVersion='0'><Course><AdditionalDataRules enabled='true'/></Course><Vehicle><Physical><Drive><Emissions emissionClass='EURO_3'/><Engine cylinderCapacity='1800' fuelType='EUROSUPER' fuelConsumption='8.0'/></Drive><Weight emptyWeight='1250' totalPermittedWeight='1500' loadWeight='0'/><Axle axleLoad='0'/><Passenger maximumPermittedNumberOfPassengers='1'/><Dimension height='150' length='450' width='180'/></Physical></Vehicle></Routing></Profile>"
      }
    ]
  }
}

I don't know if anyone changed the Default Profile but I guess that it was not altered - here is the Content of the Default.xml:

I think xRoute blocks all Segments that have an feature as soon as I activate PTV_TruckAttributes.

[Joost]

I can't explain the behavior. Looking at your request and default profile this should not happen. My best guess is that there is something wrong with you map installation. I would recommend that you create a support package as described in https://xserver.ptvgroup.com/forum/view ... f=43&t=474 and contact your normal support to open a ticket so they can investigate further.

[fstrahberger]

Many thanks I will do so
